The Rap on Berries



I have to admit the "what's cooking" question can challenge the best of us in the food universe, but a visit to the farmer's market can provide the solution in solving this dining dilemma. On my most recent visit I was drawn to the raspberries and blueberries.

The berry family has plenty of positives to benefit those on the path to well-being. They are low in calories, high in Vitamin C, fiber and folate. Additionally they contain heaps of antioxidants which aid in heart health, boosting the immune system, reducing inflammation and bad cholesterol and preventing blood clots. Adding to these umbrella benefits, the individual berries bring other health benefits to the table.

Raspberries are available in red, gold, purple and black, but the reds are the most popular. Raspberries are low in calories, and sodium; they are an excellent source of vitamin C, and a good source of carbohydrates and dietary fiber. Red raspberries also contain manganese, copper and Vitamin K. The richly colored red raspberry is high in both antioxidants and phytonutrients. Phytonutrients are defined by the American Cancer Society as plant compounds that include lycopene, resveratrol and carotenoids that are thought to have health protecting qualities.

The phytonutrients contained in raspberries aid in lowering the risk of chronic diseases such as type 2 diabetes, hypertension, and atherosclerosis. Though the research is continuing recent data indicates the potential for the fruit to play a role in obesity management.

Raspberries are delicate and should be gently washed in cool water and patted dry just before using them. They are more flavorful if allowed to come to room temperature before eating, rather than eating them as soon as they come out of the refrigerator.

Blueberries, labeled as one of the "superfoods" are also high in antioxidants including the phytonutrient anthocyanins. It is the anthocyanins that give the fruit the deep blue-purple color. The fruit is low in calories, sodium-free and a good source of vitamins C and K, manganese, fiber and copper.

Blueberry consumption is linked to antioxidant support, with a protective effect on the entire body in addition to the cardiovascular system. There is evidence that blueberries can protect the retina from damage from sunlight, and assist in maintaining the blood-sugar balance in people affected by type 2 diabetes or who are insulin resistant. Recent research indicates that consumption of blueberries may play a role in improving memory and delaying the onset of age-related cognitive problems.

As with raspberries, blueberries require gentle washing and patting dry just before using, they should be stored in the refrigerator. Blueberries can be frozen but for optimum nutrition content, fresh is best.

As for what's cooking-fresh berry salads tossed with arugula and assorted baby lettuce plus toasted nuts; berries and cottage cheese or Greek-style yogurt; fruit smoothies made with almond milk; grilled pork tenderloin with blueberries or raspberries; whole-grain pizza spread with Greek-style yogurt, and toppings of thin-sliced ham and berries of course!

Take Away: Raspberries and blueberries have nutrient star status. Add them to your meals as part of your well-being lifestyle plan.

Antioxidant Vitamins - Foods That Fight Wrinkles?

A simple diet adjustment of whole foods that are rich in antioxidant vitamins can make an enormous difference in the skin's outward reflection. Realizing which stressor(s) are negatively impacting your skin and taking action against them will help you defy the odds of premature aging of the skin and wrinkles. Several factors play a role in the appearance of fine lines and wrinkles:
Sun damaged skin
Free Radicals
Genetics
Hormones
Dehydration
Cigarette smoke
Chemical exposure
Environmental toxins
Vitamin C is a powerful antioxidant known to support collagen production. Sun exposure dehydrates, dries your skin causing free radicals, and depletes collagen; leaving it loose, weak and wrinkled. Collagen is a protein, which provides the primary part of the infrastructure and makes up approximately 75% of the skin. Healthy levels of collagen give the appearance of a smooth, plump appearance. Ultraviolet radiation, or excessive sun exposure is the primary cause of skin damage and can lead to skin cancer.
Wrinkles result from free radical damage and antioxidant vitamins neutralize free radicals. A free radical is an unstable oxygen molecule that is missing an electron. It scavenges and robs from others in an effort to become stable. In turn, after successfully "robbing", the free radicals cause other molecules to become unstable and the new free radicals begin the search for electrons and stability. This vicious cycle can alter genetic material and damage cell function. A free radicals worst enemy is an antioxidant.
Based on my research on the topic of genetics and foods rich in antioxidant vitamins, the following is what I have learned. Research proves that some individuals lack DNA repair enzymes that are responsible for protecting the skin from free radicals (such as those produced by overexposure to the sun). People who lack the genes for these repair enzymes run a higher risk of developing skin cancer. You cannot change your DNA, but you protect your entire body and can stop additional free radical damage by consuming antioxidant and vitamin rich foods. Provide your skin with the best self-defense it needs to fight aging, wrinkles, and potentially skin cancer.
Other aging culprits at work on our skin in need of antioxidant protection include those from toxic sources. Cigarette smoke and exposure to chemicals either indoors or environmentally are among the highest on the list. Toxic chemicals can damage skin cells reducing their ability to function properly. The result of poorly functioning skin cells is increased inflammation, infection, and a loss in structure. Visually, your face will look puffy or display increased blemishes and/or wrinkles.
As we age, the need for powerful antioxidants and vitamins increases due to fluctuations in hormone levels, which can alter skin metabolism of collagen and elastin. Elastin is what gives your skin its ability to stretch and then return to its natural state. Changes in collagen and elastin formation leads to fine lines and wrinkles. Menopause is of particular concern due to the hormone changes in estrogen production.
Foods that are vitamin-rich with a high antioxidant value are extremely beneficial and can come from a variety of different sources. To name a few, the following are among the top antioxidant wrinkle fighting fruits: acai, acerola, apples, apricots, blackberries, blueberries, cantaloupe, wolfberries (goji berries), kiwi, and tomatoes.
The best vegetables with vitamins and antioxidants for you skin are: bell peppers, brussels sprouts, carrots, garlic, kale, onions, and spinach.
Lastly, the top antioxidants to prevent aging and wrinkles in terms of nuts, seeds, and beverages are: almonds, flaxseeds, sunflower seeds, chocolate (dark) green tea, oats, and tuna.
If you cannot or do not wish to alter your diet, but want to supercharge your immune system, prevent premature aging of the skin, and/or free radical damage; choose antioxidant vitamins or supplements that are whole food based packed with plenty of fruits and vegetables for maximum protection.
